Is it just me or do the Evil Revolt numbers not add up?
Wheelbase seems to short for given head angle, TT, etc.
Cool resource though, thanks.

60.5* HA on the Orange?? Really?
Cool idea though, thanks for putting it together. Mondraker anyone? Canfield? Foes? Morewood Izumi?

super cool and helpful chart, especially since this stuff comes up on an almost weekly basis. Just one suggestion, you should add headtube length and diameter, not the most necessary measurements but helpful none the less.
Aight, I added headtube diameter and headtube length. also created a form to submit entries.. I think I'm going to lock the main spreadsheet from editing and handle any additions through the form.
Location of the form:

Yeah...with the 1.5 degree eccentric headtube insert and the shock mounting shuttle gives a whole ton of adjustment for headtube angle, and bb height. Chainstay length also grows with the lower/slacker shuttle settings.
I also vote for more people to plug in reach and stack measurements, especially on the more common bikes (sundays, turners) as most people are familiar with the sizing on these bikes and are a good baseline.
On the same note, canning the effective/acutal tt measurements and adding real world wheelbase lengths and front-center measurements would be nice too.

Opened it back up for editing.. If we can get the reach/stack measurements all entered in, I'll hide the TT and Actual TT measurements.. As far as real world wheelbase.. I have no problem with people entering real world geometry numbers in as long as it's noted in the Setting/Notes column..
please do not delete/hide anything. what may not be relevant to you, may be to others
Well I wouldn't delete it, hide it with the option to unhide it if you wanted to see TT/Actual TT.
great idea thanks for setting this up
I second this; with not all companies using reach and stack, as well as the public not all using it just keep it around
What an awesome chart and idea. Thanks to all the contributors!
inches are a pain for bike geo. (I am American and used to inches, btw.)
Yeah I had to go through and convert all the numbers to inches for the LaPierre, not that it matters as you can't buy it in the US anyway.
Did some more tweaking.. the form is working @ 100% now.. Added Zumbi, and the Gambler/Voltage FR that was submitted via the Form.
66º
good god, no!
That's what the site says though I think Pawel hasn't updated it as the 5mm bb drop from last year or so (not sure) is also not there.66º
yeah Zumbi was submitted via the form.
ive read this article http://raceface.com/riders/?p=1598 and there says that the new demo have 13"bb ... but there is a "ps" (in the end) saying about a 13.5"... i dont know very much about demos..but in this new model we can set the bb height?!
I have one, I know
2 people were kind enough to add the Rocky Mtn Flatine WC and the GT Fury via the form.. just updated the main spreadsheet.
Cool thread with no BS information. Should be good for the industry too to see what the competition is up to.
Bike PMs from all over the industry are probably very, very thankful right about now...
bump for a sticky
How is bb rise/drop interpreted? I'm not sure what it means or how to understand the bb height from this measurement.
I believe they are based on the lowest BB height chip and the slackest head angle insert..
Added the Summum(super adjustable), and for some controversy added the 2951..
I'm pretty sure BB rise is the measurement of how far above the horizontal line between the two (wheel) axles the BB is. So for every bike on that list except the 2951, just add 13".
I don't think you use straight +13" with tire size/profiles being different and all..
ah gotchya. thanks guys
No Chumba Zulu?
submit it via the form!
This chart is a sick idea! Good work
why no sticky action on this thread?
